Abstract: A virtual world simulation system builds worlds from cells. Each cell is assigned parameters such as resource type, temperature, pressure, density, adhesion, or support, etc. The parameters for a cell are updated using the parameters of surrounding cells. Properties for groups of cells of one or more group sizes can be aggregated to form influence maps at one or more scales. The aggregated properties of feature maps may be used to update properties of cells or objects within the corresponding region of the virtual world.

Abstract: A neural network based memory system with external memory for storing representations of knowledge items. The memory can be used to retrieve indirectly related knowledge items by recirculating queries, and is useful for relational reasoning. Implementations of the system control how many times queries are recirculated, and hence the degree of relational reasoning, to minimize computation.

Abstract: A system configured to provide one or more virtual spaces that are accessible to users. The virtual spaces may be provided such that an enhanced level of interactivity between the virtual spaces and the Web, including resources that communicate with the system via the Internet (e.g., via users, websites, webpages, other web resources, etc.) and/or other networks. To provide this enhanced level of interactivity, the system may enable interactions between an instance of a virtual space and the Web (e.g., queries, commands, communication, administrative controls, etc.) via a standard web protocol, such as a HyperText Transfer Protocol (e.g., http, https, etc.) and/or other standard web protocols. Since interactions take place between the instance of the virtual space and the Web via a standard web protocol, the instance of the virtual space may interact directly with Web resources such as web servers, web browsers, websites, webpages, and/or other Web resources.
